The Cuban missile crisis easily could have resulted in a nuclear war. Americans felt especially threatened, with those missiles just one hundred fifty kilometers from the Florida coast. But the crisis ended after a week. Khrushchev agreed to remove the missiles if the United States agreed not to interfere in Cuba.

Some progress was made in easing Cold War tensions when Kennedy was president. In nineteen sixty-three, the two sides reached a major arms control agreement. They agreed to ban tests of nuclear weapons above ground, under water, and in space. They also established a direct telephone link between the White House and the Kremlin.

Relations between East and West also improved when Richard Nixon was president. He and Leonid Brezhnev met several times. They reached several arms control agreements. One reduced the number of missiles used to shoot down enemy nuclear weapons. It also banned the testing and deployment of long-distance missiles for five years.

A major change in the Cold War would take place in nineteen eighty-five, when Mikhail Gorbachev became leader of the Soviet Union. He met four times with President Ronald Reagan. Gorbachev withdrew Soviet forces from Afghanistan. And he signed an agreement with the United States to destroy all middle-distance and short-distance nuclear missiles.
